Emergency c section 10 weeks early now 5 weeks still swollen and in pain is this normal ?

My lovely boy is nearly 6 weeks old n after many weeks is due to come home. 
I however still don't feel great I no it's early but my stomach is flat first thing in morning then swells to like I'm four months pregnant by end of the day. It burns and hurts 
Will it ever go down ? Has anyone had this too ? Did it go ?
